Chapter 1: Behaviour in the Greeting
Muwatta Malik 1884
Yahya related to me from Malik from Zayd ibn Aslam that the  Messenger of Allah  ﷺ  said, "The one riding greets the one walking, and when one of a group of people gives a greeting, it is enough for all of them."
                    حَدَّثَنِي عَنْ مَالِكٍ، عَنْ زَيْدِ بْنِ أَسْلَمَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ 
" يُسَلِّمُ الرَّاكِبُ عَلَى الْمَاشِي وَإِذَا سَلَّمَ مِنَ الْقَوْمِ وَاحِدٌ أَجْزَأَ عَنْهُمْ " .
